IMPORTANT
WARNING
Read these instructions carefully before installing or trying to operate a vent-free gas heater in this firebox.
• Any change to this heater or its controls can be dangerous.
• Improper installation or use of the heater can cause serious injury or death
from fire, burns, explosion or carbon monoxide poisoning.
• Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter
burner flame patterns.
• Do not use a blower insert, heat exchanger insert or other accessory, not
approved for use with this heater where applicable.
1. Due to high temperatures, the appliance be
located out of traffic and away from furniture and
draperies.
2. Children and adults should be alerted to the hazard
of high surface temperature and should stay away
to avoid burns or clothing ignition.
3. Young children should be carefully supervised when
they are in the same room with the appliance.
4. Do not place clothing or other flammable material on
or near the appliance.
5. Any safety screen or guard removed for servicing an
appliance, must be replaced prior to operating the
heater.
6. Installation and repair should be done by a qualified
service person.
7. To prevent malfunction and/or sooting, an unvented
gas heater should be cleaned before use at least
annually by a professional service person. More
frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is
imperative that control compartments, burners and
circulating air passageways be kept clean.
8. CARBON MONOXIDE POISONING: Early signs of
carbon monoxide poisoning are similar to the flu with
headaches, dizziness and/or nausea. If you have these
signs, obtain fresh air immediately. Have the heater
serviced as it may not be operating properly.
9. This unit complies with ANSI Z21.11.2 unvented heaters standard, latest edition.
10. Do not install the CFX Model in a bathroom or bedroom.
20301726
11. Correct installation of the ceramic fiber logs, proper
location of the heater, and annual cleaning are necessary to avoid potential problems with sooting. Sooting,
resulting from improper installation or operation, can
settle on surfaces outside the fireplace. See log placement instructions for proper installation.
12. Avoid any drafts that alter burner flame patterns. Do not
allow fans to blow directly into fireplace. Do not place
a blower inside burn area of firebox. Ceiling fans may
create drafts that alter burner flame patterns. Sooting
and improper burning will occur.
13. Caution: Candles, incense, oil lamps, etc. produce
combustion by-products including soot. Vent-free
appliances will not filter or clean soot produced by
these types of products. In addition, the smoke and/or
aromatics (scents) may be reburnt in the vent-free
appliance which can produce odors. It is recommended
to minimize the use of candles, incense, etc. while the
vent-free appliance is in operation.
14. An unvented gas-fired heater uses air (oxygen) from
the room in which it is installed. Provisions for adequate
combustion and ventilation air must be provided. See
installation guidelines.
15. This heater shall not be installed in a room or space
unless the required volume of indoor combustion air is
provided by the method described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, the International
Fuel Gas Code or applicable local codes.
16. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
17. Unvented gas heaters are a supplemental zone heater.
They are not intended to be a primary heating appliance.
18. Unvented gas heaters emit moisture into the living
area. In most homes of average construction, this
does not pose a problem. In houses of extremely
tight construction, additional mechanical ventilation is
recommended.
19. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, films or bonding agents. These chemicals are not
harmful but may produce annoying smoke and smells
as they are burned off during the initial operation of the
appliance; possibly causing headaches, or eye or lung
irritation. This is a normal and temporary occurrence.
The initial break-in operation should last two to three
hours with the burner at the highest setting. Provide
maximum ventilation by opening windows or doors to
allow odors to dissipate. Any odors remaining after this
initial break-in period will be slight and will disappear
with continued use.
20. Input ratings are shown in BTU per hour and are for
elevations up to 2,000 feet. For elevations above 2,000
feet, input ratings should be reduced 4 percent for each
1,000 feet above sea level. Refer to the National Fuel
Gas Code.
21. The appliance and its appliance main gas valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).
IMPORTANT SAFETY INFORMATION
22. The appliance must be isolated from the gas supply
piping system by closing its equipment shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig
(3.5 kPa).
23. Do not use this room heater if any part has been under
water. Immediately call a qualified service technician
to inspect the room heater and to replace any part of
the control system and any gas control which has been
under water.
24. Never burn solid fuels in a fireplace where a unvented
room heater is installed.
25. Always have a fireplace screen in place when the
appliance is in operation, and unless other provisions
for combustion air are provided, the screen shall have
an opening(s) for induction of combustion air.
26. Do not fill spaces around the firebox with insulation or
other materials. These spaces must be maintained to
prevent the firebox from coming in contact with combustible materials.
This appliance may be installed in an aftermarket,
permanently located, manufactured (mobile)
home, where not prohibited by local codes.
This appliance is only for use with the type of
gas indicated on the rating plate. This appliance
is not convertible for use with other gases.

CONNECT THE GAS
check gas type
Use proper gas type for the fireplace you are installing. If you have conflicting gas type, do not
install fireplace. See dealer where you purchased the fireplace for proper fireplace for your
gas type or conversion kit.
A qualified installer or service person must
connect appliance to gas supply. Follow
all local codes.
CAUTION
WARNING
Installing gas piping to fireplace / burner system location
For propane/LP units, never connect
fireplace directly to the propane/LP supply.
This burner system requires an external
regulator (not supplied). Install the external
regulator between the burner system and
propane/LP supply.
INSTALLATION ITEMS NEEDED
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator • Piping (check local codes)
•Sealant (resistant to propane/LP gas)
(supplied by installer)
• Equipment shutoff valve*
•Test gauge connection*
• Sediment trap (recommended) • Tee joint
•Pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.

CAUTION
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the
vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.
Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be used per National Fuel Code, Section
2.6.3, providing gas meets hydrogen sulfide
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data
plate) at the maximum flow rate (BTU/hr).
Undue pressure loss will occur if the pipe
is too small.
When using copper of flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.

CAUTION
WARNING
CONNECT THE GAS
A manual shutoff valve must be installed
upstream of the appliance. Union tee
and plugged 1/8” NPT pressure tapping
point should be installed upstream of the
appliance. Figure 13
A listed manual shutoff valve must be installed upstream of
the appliance. Union tee and plugged 1/8" NPT pressure
tapping point should be installed upstream of the appliance.
Figure 13
IMPORTANT: Install main gas valve (equipment shutoff valve)
in an accessible location. The main gas valve is for turning on
or shutting off the gas to the fireplace.
CAUTION
NOTE: The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.
Since some municipalities have additional local codes it is always best to consult your local authorities
and the current edition of the National Fuel Gas Code ANSI.Z223.1, NFPA54. In Canada CSA-B149
(1 or 2) Installation Code.
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
Check your building codes for any special requirements for locating equipment shutoff valve to
fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe.
Excess sealant in pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 13. Locate
sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel
supply and burner system. Locate sediment trap/drip leg where trapped matter is not likely to freeze.
A sediment trap collects moisture and contaminants and keeps them from going into the burner
system gas controls. If sediment trap/drip leg is not installed or is installed wrong, burner system
may not run properly.

LOG PLACEMENT
CAUTION
The positioning of the logs is critical to
the safe and clean operation of this heater.
Sooting and other problems may result if the
logs are not properly and firmly positioned
in the appliance. Never add additional logs
or embellishments such as pine cones,
vermiculite or rock wool to the heater.
WARNING
WARNING
Before you begin — This unit is supplied with a set of three ceramic fiber logs. Do not handle these
logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic fibers. After
handling logs, wash your hands gently with soap and water to remove any traces of fibers.
Failure to position the parts in accordance
with these diagrams or failure to use only
parts specifically approved with this heater
may result in property damage or personal
injury.
DO NOT sprinkle volcanic rock on the logs
or around the pilot or the main burner. This
may cause sooting. Only place volcanic
rock on the floor of the fireplace.
During initial operation of the new heater,
burning logs will give off a paper burning
smell and orange flames will be present.
Simply open the windows for a few hours
to vent the odor.

OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the
fireplace. Do not place a blower inside the burn area of the firebox. Ceiling fans may create drafts
that alter flame patterns. Sooting and improper burning will result.
During manufacturing, fabricating and shipping, various components of this appliance are treated
with certain oils, films or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance, possibly
causing headaches or eye or lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last two to three hours with the burner at the highest setting.
Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors
remaining after this initial break-in will be slight and will disappear with continued use.
